Benefits of Cold Plunge
Faster Recovery
Cold immersion after hard training reduces soreness in the days that follow.
Deeper Sleep
A drop in core temperature is one of the body's sleep cues. An evening plunge preps you for deep sleep.
Sharper Mornings
Cold exposure raises circulating norepinephrine, which most people feel as clean, jittery-free alertness.
A daily Reset
You can do anything for 2 minutes. Prove it every day and go out and conquer your schedule.

Yes. The Unicorn is designed for both indoor and outdoor use, making it suitable for bathrooms, home gyms, patios, decks and other appropriate cold-plunge locations.
For outdoor installations, place the chiller on a stable, level surface with adequate airflow around the unit. As with any electrical appliance used around water, the electrical connection should be appropriately protected and the unit should be operated according to the supplied installation and safety instructions.
The Unicorn is portable and equipped with wheels, making it easy to reposition when needed.
Your Unicorn chiller will need to be plugged into an outlet with a dedicated 120V 15A circuit. The term "dedicated" means that the electrical circuit for your chiller can not be used for any other electrical items.
